Abstract
A sealed, high volume, high velocity, vented 180 degree radius turnaround anti-reversionary flow correcting filtering device with no moving parts for improving induction velocity comprised of 2 flared pipes forming a radius turnaround Venturi configuration wherein the head intake runner wall helps form the coaxial cylindrical air curtain, with a funneled restriction point, 2 vacuum points and mounting legs for positioning and creating turbulence streams, for installation in 4 stroke combustion engine ports of both round and non-round designs. This invention increases engine performance and efficiency, and decreases wasteful and atmospheric-polluting exhaust emissions. There have been no prior 180 degree turnaround, high velocity, high volume reversion filtering devices in use up to and through the 1998 motor vehicle year.
